ANNALES HISTORICO-NATURALES MUSEI NATIONALIS HUNGARICI Tomus 76. Budapest, 1984 p. 239-244. Flea species new for the Hungarian fauna (Siphonaptera), VII.* by A. DUDICH, Stare Hory & I. SZABÓ, Budapest Abstract — Five flea species are reported new to the fauna of Hungary: Atyphloceras nuperus (JORDAN), Rhadinopsylla mesoides SMIT, Amalaraeuspenicilliger kratochvili ROSICKY, Doratopsylla dasyenema cuspis (ROTHSCHILD) and Nosopsyllus mokrzeckyi(WAGNER). Locality data, taxonomical remarks and zoogeographical evaluations are given for every species in question. With 16 figures. The following flea species new for the Hungarian fauna were obtained from the bodies of small mammals (insectivores and rodents) in the last two years: Atyphloceras nuperus (JORDAN) 1931 — L o c a 1 i t i es. 1 çf : Királyháza, Rózsáspatak vgy., 500 m (Börzsöny Mts., Com. Nógrád) 10 October 1983, leg. STOLLMANN, host : C. glareolus (SCHREB.). 2 9 0 : Mátraalmás, 700 m (Mátra Mts., Com. Nógrád), 12-13 October 1983, leg. MÉSZÁROS and STOLLMANN, host: C. glareolus (SCHREB.). 2 9 9 : Nagyvisnyó, Bán patak vgy., 600 m (Bükk Mts., Com. Heves) 16 October 1983, leg. STOLLMANN, host : C. glareolus (SCHREB.). This mountain species was first announced from the Western Carpathians by JURIK (1960). Since then we have found specimens from more than forty mountain localities that are above 700 m. It was ascertained that the area of distribution of A. nuperus in Central Europe basically corresponds with the natural distribution of fir-tree {Abies alba L.) (DUDICH 1983). Our material was collected in pure beech forests, but maybe, fir was certainly distributed in the mid-Holocene and probably also in historical times. A. nuperus as a stenochronous species is a member of the winter fleasynusia of the bank vole in the highest mountain sites in Hungary. For this reason hitherto it has not been detected. Our few specimens were sampled along with the following flea species: Ctenophthalmus agyrtes peusianus ROSICKY, Ctenophthalmus c. congener (ROTHSCHILD), Hystrichopsylla t. talpae (CURTIS), Peromyscopsylla b. bidentata (KOLENATI), Peromyscopsylla fallax (ROTHSCHILD), Rhadinopsylla integella (ROTHSCHILD). In the Mátra Mts. it has been found with Ctenophthalmus obtusus JORDAN et ROTHCHILD, Rhadinopsylla mesoides SMIT, and Amalaraeus penicilliger kratochvili RosiCKY. Indexes of infestation (calculated for the bank vole only) on the whole were low: extensity 1.82.4%, mean intensity 0.018-0.047. Low degree of dominance was calculated, too (D = 1.1-2.5). There were 183 specimens of C. glareolus and 71 specimens of other members of the family Arvicolidae (Pitymys subterraneus DESÉLYS-LONGCH. and Microtus arva/is PALLAS) examined totally. The occurrence of A. nuperus in Hungary can be expected in the Kőszeg Mts. (foothill of the Alps, in the western part of our country) and probably in the Zemplén Mts. as a continuation of the distribution of this species from Slovakia. Since A. nuperus was not mentioned in the volume of Siphonaptera — Fauna Hungáriáé (Szabó 1975) the morphological patterns necessary in the identification of this species are given (Figs. 1-4). Rhadinopsylla mesoides SMIT, 1957 — Locality. 1 çf '• Mátraalmás, Szuha patak vgy., 700 m (Mátra Mts., Com. Nógrád), 13 October 1983, leg. KOVÁCIK, host : C. glareolus (SCHREB.). This rare mountain species is distributed in the great European mountain ranges (Pyrenees, Alps, Carpathians and Balkan mountains). ROSICKY (1950) first recorded Rhadinopsylla mesa J. et R. from the High Tatra Mts. in the Western Carpathians. Since it is known only from a few localities in the Vihorlat Mts. (DUDICH 1984a); Kremnické vrchy Mts. (JURIK 1960); Polana Mts. (DUDICH 1984b); Western Tatra Mts. (DUDICH, 1982) and Javorniky Mts (RYBA et al. 1975) all the localities are in Czechoslovakia. Only single specimens of Rhadinopsylla mesoides had been collected rarely from the fur of the main host species, abundant collections were made from the winter-nests of the bank vole (Ryba et al. 1975). R. mesoides is a member of the winter-synusia of nests of C. glareolus (SCHREB.). Our only specimen was collected with other late autumn and winter flea species : A. nuperus (Jordan); * Report No. 10 from the project "Complex parasitological studies on small mammal populations", a co-operation between the Hungarian Natural History Museum, Budapest and the Institute of Experimental Biology and Ecology, Slovak Academy of Sciences, Bratislava.
